The syntax is as follows:
if ${condition_command}; then
starts the if statement where${condition_command}
represents the condition that is evaluated.${echo "Condition is true"}
is the command that will be executed if the condition evaluates to true. It will display "Condition is true".else ${echo "Condition is false"}
specifies the command that will be executed if the condition evaluates to false. It will display "Condition is false".fi
denotes the end of the if statement.

. If it evaluates to true, it executes the command echo "Condition is true"
. Otherwise, it executes the command echo "Condition is false"
.
